How can one troubleshoot and debug issues with database entries not being inserted in PHP?

Issue: Database entries not being inserted in PHP can be due to various reasons such as incorrect SQL syntax, connection errors, or data validation issues. To troubleshoot this problem, check the SQL query for errors, ensure that the database connection is established correctly, and validate the data being inserted to match the database schema. 

// Example code snippet to troubleshoot database entry insertion issue

// Establish a database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Sample SQL query to insert data into a table
$sql = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')";

// Execute the SQL query
if ($conn->query($sql) === TRUE) {
    echo "New record inserted successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

// Close the database connection
$conn->close();
